I sort my risks in descending order with the Risk Score as the primary sort. Risk is increased with speed or bald tires (higher probability of slipping and greater damage on impact). Once you have rated each risk, calculate the Risk Score as Probability x Impact. Rate probability and impact using a scale such as 1 to 10. The impact is the consequence or effect of the risk, normally associated with impact to schedule, cost, scope, and quality. Probability is the likelihood that a risk will occur. This two-dimensional technique is used to rate probability and impact. I normally use this technique with larger, more complex projects and with teams that have experience with risk assessments. This scale allows greater discrimination than the commonly used Low, Medium, and High scale. This one-dimensional technique involves rating risks as: I use the KISS (Keep It Super Simple) Method on smaller projects and with teams that lack maturity in assessing risks. The table above does not assign a categorical rating (i.e., High, Medium, or Low) to a risk event that is certain not to occur.A risk event that is certain to occur has, by definition, probability equal to one. Two Methods of Qualitative Risk Analysis 1. A risk event that is certain not to occur has, by definition, probability equal to zero.In this case, we say the risk event does not exist. If not, define the criteria for your scale. the Probability/Impact Assessment.īe sure to specify your risk analysis technique(s) in your Risk Management Plan as you assess your risks, capture and maintain your risk ratings in your risk register.Ĭheck with your organization to determine whether there is a definition of risk scales. Let’s look at two qualitative risk evaluation methods: 1. Assign your most skilled, knowledgeable resources to the projects with the greatest risk. This aids us in determining the amount of effort to invest in developing response plans. The goal of evaluating risks is to discriminate between one risk and another. What are the vital few things that we should do that will have the greatest impact on minimizing threats and maximizing opportunities? Eighty percent of the impact will come from twenty percent of the risks. This aids in determining where you will spend your limited time and effort. Risk management does not imply that no risks are taken it means that the risks taken should be calculated risks. Prioritization is a way to deal with competing demands. The FMEA is in principle a full inductive (forward logic) analysis, however the failure probability can only be estimated or reduced by understanding the failure mechanism. You cannot respond to all risks, neither should you. An FMEA is used to structure mitigation for risk reduction based on either failure (mode) effect severity reduction or based on lowering the probability of failure or both.
